Adaptive Man-Machine Interaction in Information Retrieval; A Dissertation in Electrical Engineering.
Edwards, John S.
Three specific contributions to the field of information retrieval are presented. The first two describe the establishment of an adaptive, interactive man-machine dialogue that produces a form of unsolicited librarian-like assistance for the user in his selection of index terms to characterize an indexing function. The data set upon which the system rests is prepared in a semi-automatic manner from preselected samples of natural language text in machine readable form. The first contribution concerns setting up this data set; the second deals with the implementation of a man-machine dialogue. The algorithm that constitutes the third contribution extracts the cyclic sets of terms from a symmetric relation table. It is shown how this technique helps the formation of a consistent and complete table of synonyms. The system has been implemented on a PDP8-7040 computer complex and is programmed for the most part in L6-MAP. (Author)
